To all whom it may concern;

Be it known that I, JOSEPH W; BAKER, a& citizen of the United States,residing at Corry, in the county of Erie and State of Pennsyl-- Vania,have invented certain new and useful Improvements in Washing-Machines;and I' do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters of reference markedthereon, forming part of this specilication.

My invention consists in the improvements in washing-machineshereinafter set forth and I explained, and illustrated in theaccompanying drawings, in which- Figure 1 is a perspective view of my improved washing-machine with a wringer attached thereto. Fig. 2 is across-section of my machine on the line so a: in Fig. 1, showing theflexible removable wash-board raised up from the bottom, Fig. 3 is across-section of my machine with the wringer attached on the line a: a:in Fig. 1, with the roller mechanism removed. Fig. 4: shows a section ofmy improved flexible removable Wash-board.

Like letters refer to like parts in all the figures.

In the construction of my invention shown in the drawings, A is a tub,the bottom A of which is circular, made of sheet metal in the shape ofahalf-ellipse, as and for the purpose hereinafter set forth, secured tothe ends B, so

0 O are the upright posts of the frame, each provided with feet 0 c, andsecured together at their upper ends by cross-bars D D and at theirlower ends by means of a cross-bar E, so as to form a firm andsubstantial frame.

To the central part of the upper edges 1) b of the ends B B of the tubA,I secure journals dd, which project outward into bearings in the uprightposts 0 C, so that the tub A will oscillate freely thereon and may bereadily oscillated by means of the handles 6 e thereon.

In the bottom of the tub A, I place a flexible removable wash-board F,made of fluted lags secured together by a strip of flexible material G,nailed across their ends on the back side thereof, and I removablysecure this board in place in the tub A by means of stops. 9 hfsecuredto the inside of the tub-bottom A, one of these stops 9 beingpermanently secured'in place, and the other h hinged to a strip H,secured to the inside of the tub-bottom, so that by raising the stop hthe end of the flexible board can be raised, as illustrated in Fig. 2,and withdrawn from the tub.

Across the top of each side of the tub A, I secure strips of board I,which project over the inside of the tub sufficiently to prevent thewater from splashing over the side of the tub When it is beingoscillated.

To the cross-barsD D of the frameI secure tongued or grooved guides J J,which project downwardly therefrom into the tub A, near the ends B Bthereof, within which guides are placed vertically-sliding bearings L L,moving independently of each other, in the lower ends of which thejournals of the compressionroller M are mounted. These sliding bearingsL L are normally'forced downward by means of the spiral springs 10 70,secured to the upper ends of the sliding bearings L L and to the uprightposts C C of the frame by means of hooks i 2', so as to firmly press theroller M down upon the fluted board F in the semi-elliptical-shapedtub-bottom A, or upon clothing placed thereon, the bearings L L of theroller M and the springs 10 k thereon allowing the ends of the rollers Mgreat freedom of movement to rise or fall independently of each other,so as to pass over bunches of clothes, as required; and on the tub Abeing oscillated the roller M travels to and fro over theelliptical-shaped wash-board F,with the pressure of the springs 70 7cgradually decreasing as the roller travels from the center toward theends of the wash-board and increasing as it travels from the ends towardits center, this feature being accomplished by the half-elliptical shapeof the tub-bottom A, thus bringing the greatest pressure of the rollerupon the central portion of the tub, where the greatest amount of workis to be done, and reducing it toward the ends of the board, therebyequalizing and greatly diminishing the power required to operate themachine.

hen it is desired to raise the roller M off of the board F, as shown inFig. 2, the sliding bearings L L are raised up and small pins m m placedin holes therein, which retain the roller M in the position shown inFig. 2.

The roller M, Imake with a longitudinallyfluted periphery, and boretherein a large number of radial holes N, which do not passentirelythrough the roller, so that as it is ro tat'ed the airin the holes N isdischarged under the Water used in the tub, so as to better agitate itand assist the process of washing thereby.

To the upper part D D of my machineframe I secure a wringer O, ofordinary construction, and to theouter edgeof the apron P thereof Ihinge an extension Q, by means of small hooks n, so that it can heremoved or folded back against thewringer 0 when desired, the object anduse of this extension Q being to convey the clothes over the rear edgeof the tubA When the wringer O is'being used.

I I am aware of the patent to Christopher, No.

177,374, dated May 16, 1876, and therefore I do not claim,broadly, anoscillating tub having a circular fluted Wash-board and acompression-roller operating thereon; but

hat I do claim, and desire to secure by Letters Patent of the UnitedStates, is

The combination, in a Washing-machine, of an oscillating tub A, having asemi-ellipticalshaped bottom A and a fluted Wash-board F therein, With afluted compression-roller M, mounted in vertically-moving bearings L L,having compression-springs la 76 secured to said bearings and to theframe, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two Witnesses.

JOSEPH V. BAKER.
